Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1 and fig. 2, which are a schematic structural diagram of a roll bearing dismounting device 1 according to the present invention and a partial enlarged view thereof, respectively.

The roller bearing dismounting device 1 comprises a positioning seat 2, a top plate 3, a pulling plate 4, a pulling arm 5, an oil cylinder 6 and support legs 7. For the sake of convenience, a roller 8 and a bearing 9 are additionally introduced.

The positioning seat 2 comprises a base 21, an electric lifting rod 22, a supporting plate 23 and a controller 24. The top of base 21 is vertically equipped with three electric lift rod 22, each electric lift rod 22's top is equipped with one respectively backup pad 23. The three support plates 23 have different structures and are respectively used for being connected with the top plate 3, the oil cylinder 6 and the support legs 7. The controller 24 is also arranged on the top of the base 21, and is connected with the three electric lifting rods 22 through a circuit to manually control the lifting. The circuit structure can be designed by those skilled in the art according to actual situations, and will not be described herein.

The top plate 3 is a circular steel plate, and a circle of annular groove 31 is welded at the circle center of one surface and used for being connected with a piston rod of the oil cylinder 6. Six mutually independent elongated openings are radially arranged around the annular groove 31 by taking the circle center as the center.

The pulling plate 4 comprises an abutting plate 41, a connecting plate 42, a truss 43 and a connecting edge 44. The connecting plate 42 is a circular steel plate with the diameter consistent with that of the top plate, a round hole slightly larger than the diameter of the shaft neck of the roller 8 is arranged at the position of the center of the circle, and six mutually independent strip-shaped openings are radially arranged around the center of the circle. The opening does not contact the via.

The abutting plate 41 is a circular steel plate with a diameter slightly larger than that of the bearing 9, and a circular hole with a diameter larger than that of the shaft neck of the roller 8 is also formed in the circle center position. The abutting plate 41 is concentric with the connecting plate 42, and the truss 43 is welded between the abutting plate and the connecting plate.

The whole of the abutting plate 41, the connecting plate 42 and the truss 43 is divided into two halves in the radial direction. The abutting plate 41 and the connecting plate 42 are welded with one connecting edge 44 on the right side along two sides of a broken joint position. The two connecting edges 44 of the abutting plate 41 are connected through bolts, and the two connecting edges 44 of the connecting plate 42 are connected through bolts, so that the whole body is fixed.

The pull arm 5 includes a round bar 51 and a baffle 52. The round bar 51 is a strip-shaped round bar with a diameter consistent with the opening width of the top plate 3 and the connecting plate 42. One end of the round rod 51 is welded with a round baffle plate 52 with the diameter larger than that of the round rod 51; the other end is welded with a ring-shaped baffle plate 52 at the position close to the tail end, and a round baffle plate 52 with the diameter consistent with that of the ring-shaped baffle plate 52 is welded at the tail end.

The supporting foot 7 is a cylindrical steel block, the diameter of the supporting foot is slightly smaller than that of the shaft neck of the roller 8, and the length of the supporting foot is larger than the width of the bearing 9. The left end of stabilizer blade 7 has welded tapered connector 71, through connector 71 with the cylinder body of hydro-cylinder 6 links up.

In specific implementation, the disassembled roller 8 is firstly lifted and horizontally placed. The two parts of the pulling plate 4 are sleeved on the journal between the bearing 9 of the roller 8 and the main body of the roller 8, and the connecting edge 44 is provided with a bolt lock to fix the connecting edge on the journal of the roller 8. Because the diameters of the two round holes in the middle of the pulling plate 4 are slightly larger than the diameter of the shaft neck of the roller 8, the pulling plate can rotate or slide left and right on the shaft neck.

Then, the positioning seat 2 is placed, and the top plate 3, the oil cylinder 6 and the support legs 7 are placed on the three support plates 23. The controller 24 is used for adjusting the height of each electric lifting rod 22 to enable the top plate 3, the oil cylinder 6, the supporting feet 7 and the roller 8 to be coaxial, and manual fine adjustment is carried out to enable the structures to be in contact with one another.

Two ends of six pulling arms 5 are respectively inserted into six openings of the top plate 3 and the connecting plate 42. One end of one of the blocking plates 52 is clamped into the left side of the top plate 3, and one ends of the two blocking plates 52 are clamped into the two sides of the connecting plate 42.

The oil cylinder 6 is connected to an existing hydraulic system, and when the oil cylinder 6 is controlled to extend, all the mechanisms are tensioned. At this time, the positioning seat 2 can be removed and a cushion can be placed. Continuing the elongation, the bearing 9 is gradually moved out onto the foot 7. After the bearing 9 is removed from the journal of the roll 8, the structure loses support and falls onto a cushion.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification of the present invention, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
